Complete minimal surfaces and harmonic functions [Article]
(European Mathematical Society, 2012)We prove that for any open Riemann surface N and any non constant harmonic function h : N → R, there exists a complete conformal minimal immersion X : N → R3 whose third coordinate function coincides with h. As a ...

Complete minimal surfaces in R3 with a prescribed coordinate function [Article]
(Elsevier, 2011)In this paper we construct complete simply connected minimal surfaces with a prescribed coordinate function. Moreover, we prove that these surfaces are dense in the space of all minimal surfaces with this coordinate ...

Design of hardware-based security solutions for interconnected systems [PhD Thesis]
(2020-01-21)Among all the different research lines related to hardware security, there is a particular topic that strikingly attracts attention. That topic is the research regarding the so-called Physical Unclonable Functions (PUF). ...

DYKAT and desymmetrization strategies for the synthesis of axially chiral heterobiaryls [PhD Thesis]
(2020-01-31)The main objective of this PhD thesis is the development of new methodologies for the synthesis of axially chiral heterobiaryls through asymmetric functionalization of this type of systems. In this regard, the approaches ...

Finding Multiple Solutions in Nonlinear Integer Programming with Algebraic Test-Sets [Presentation]
(Springer, 2018)We explain how to compute all the solutions of a nonlinear integer problem using the algebraic test-sets associated to a suitable linear subproblem. These test-sets are obtained using Gröbner bases. The main advantage ...

Investigaciones sobre recursos abióticos en la prehistoria reciente de Tierra de Barros y Sierra Morena Occidental [Presentation]
(Csic; Museo Arqueológico Nacional, 2008)En este trabajo se presentan las investigaciones de base arqueométrica que se están llevando a cabo con objeto de conocer los sistemas de abastecimiento de recursos abióticos de las comunidades del III y II milenio ANE ...

Transgressivity in Key Functional Traits Rather Than Phenotypic Plasticity Promotes Stress Tolerance in A Hybrid Cordgrass [Article]
(MDPI, 2019)Hybridization might promote offspring fitness via a greater tolerance to environmental stressors due to heterosis and higher levels of phenotypic plasticity. Thus, analyzing the phenotypic expression of hybrids provides ...

What causes an RNA-DNA hybrid to compromise genome integrity? [Article]
(Elsevier, 2019)Transcription is a source of genome instability that stimulates mutation and recombination. Part of the damage produced by transcription is mediated by R-loops, non-B DNA structures that normally form by the re-annealing ...

Regulation of DNA end resection by cell stemness [PhD Thesis]
(2020-01-20)The ability to reprogram somatic cells into induced pluripotent stem cells (iPSCs) holds great potential for clinic applications, however, acquired genomic instability is one of the major concerns for its clinical use. The ...

Prolonged quiescence delays somatic stem cell-like divisions in Caenorhabditis elegans and is controlled by insulin signaling [Article]
(Wiley Open Access, 2019)Cells can enter quiescence in adverse conditions and resume proliferation when the environment becomes favorable. Prolonged quiescence comes with a cost, reducing the subsequent speed and potential to return to proliferation. ...

R Loops: From Physiologicalto Pathological Roles [Article]
(Elsevier, 2019-10-17)DNA-RNA hybrids play a physiological role in cellular processes, but often, they represent non-scheduled co-transcriptional structures with a negative impact on transcription, replication and DNA repair. Accumulating ...

A vanishing theorem for a class of logarithmic D-modules [Article]
(Cornell University, 2007)Let OX (resp. DX) be the sheaf of holomorphic functions (resp. the sheaf of linear differential operators with holomorphic coefficients) on X = Cn. Let D X be a locally weakly quasi-homogeneous free divisor defined by ...

The DNA damage response acts as a safeguardagainst harmful DNA–RNA hybrids ofdifferent origins [Article]
(EMBO Press, 2019-07-24)Despite playing physiological roles in specific situations, DNA–RNA hybrids threat genome integrity. To investigate how cells do counteract spontaneous DNA–RNA hybrids, here we screen an siRNA library covering 240 human ...

Hypoxia in the Initiation and Progression of Neuroblastoma Tumours [Article]
(MDPI, 2019)Neuroblastoma is the most frequent extracranial solid tumour in children, causing 10% of all paediatric oncology deaths. It arises in the embryonic neural crest due to an uncontrolled behaviour of sympathetic nervous system ...

Extracellular Vesicle-Mediated Communication between the Glioblastoma and Its Microenvironment [Article]
(MDPI, 2019)The glioblastoma is the most malignant form of brain cancer. Glioblastoma cells use multiple ways of communication with the tumor microenvironment in order to tune it for their own benefit. Among these, extracellular ...

Diversity of Sinorhizobium (Ensifer) meliloti Bacteriophages in the Rhizosphere of Medicago marina: Myoviruses, Filamentous and N4-Like Podovirus [Article]
(Frontiers Media, 2020)Using different Sinorhizobium meliloti strains as hosts, we isolated eight new virulent phages from the rhizosphere of the coastal legume Medicago marina. Half of the isolated phages showed a very narrow host range while ...
